The victim, a woman in her 30s, told police that she was waiting for a bus near a construction site at 52nd and Market in West Philadelphia, when Corley -- who is assigned to the 18th District -- offered to give her a ride to the 69th Street Terminal in Upper Darby, police sources said.

The woman said Corley instead took her to the area of the Cobbs Creek recreation center where he allegedly sexually assaulted her while he was partially clad inside his police vehicle, according to police sources.

After the assault he reportedly dropped off the victim in Upper Darby, sources said.

Sources say Corley, a four-year veteran of the force and a married father of step children, showed up at police headquarters Wednesday on allegations that he lived out of state. While there he was arrested for the alleged assault.

Corley's gun and badge were taken away. He is suspended for 30 days with the intent to dismiss, according to police.
